High efficiency alternative/renewable powered ups system

Abstract

The disclosure provides an efficient alternative energy uninterruptible power supply (UPS) system having a main first source of power coupled to an electrical load, comprising: a second source of power from stored energy coupled to the electrical load, the second source being adapted to supplement the first source and condition the power from the stored energy to predetermined conditions for the electrical load; an automatic transfer switch (ATS) coupled between the first source and the second source and adapted to control the first source coupling to the electrical load when the first source power is noncompliant with predetermined conditions for the electrical load; and a source of alternative energy coupled downstream of the ATS to the second source, the electrical load, or a combination thereof, wherein the source of alternative energy comprises a source of direct current (DC) power.

Field of the Invention[0005]The inventions disclosed and taught herein relate generally to power systems; and more specifically relate to power systems using a variety of energy sources.[0006]2. Description of the Related Art[0007]For decades, alternative energy sources have been considered in supplementing power provided by utility companies for electrical loads. Such alternative energy sources include solar energy, geo-thermal energy, wind energy, hydro energy, fuel cells, biomass and gas generated therefrom, tidal energy, and the like. To produce the necessary voltage and / or current, multiple arrays of panels, levies, dams, wind turbines, fuel cells, and so forth can be connected in series, in parallel or both, according to the needs of the system. However, the ...

Benefits of technology

[0015]The present invention provides an increased efficiency and generally lower system cost and complexity by eliminating the grid-tie inverter and providing a different configuration than the typical power system. The invention radically departs from the standard design criteria by recognizing certain well-established components can be redirected or eliminated, and still maintain high integrity power to the ultimate electrical load.

Problems solved by technology

However, the costs per kilowatt of power have commercially retarded the acceptance of alternative energy usage.

The various conversions yield power losses and other inefficiencies.

However, the conversion process from DC to AC power for the utility grid inherently causes power losses, which are believed to be about 92-95%.

Despite the availability of the alternative energy power for the electrical load, such as a data center, this alternative energy power is unavailable to the electrical load until the utility power returns.

The multiple conversions result in further loss of efficiency.

For large power systems, this loss of power can be a significant amount.
